advantages of my improved system it should be capable of usein either direction, 1 e,

either to receive an alternating 'currentan give out a direct current or receive a. direct current and give out an alter-natin current,

or, speaking more broadly, 'to receive. a-current of one kind or at one pressure and give v out-a current of another kind or-at aii'othcr pressure.-' '7'311Cl8 are direct current leads connected to B, and connected across these leads is an equalizing circuit containing the storage-batteriesD. Between the rectifying," device and the storage batteries is the booster .E;

The essentlal point about regulatingdevice F which is acted uponby this-regulating device is that" it .shall be so connected and constructed that it will be vafi'ected by changes of electrical condition in the alternating circuit while it in turn" 'shall control the battery current, in the case shown byv regulating the voltage ofboo'ster, E, so that the battery. may effectively actas an equaliier of the load on the generator A.

1 consider it preferable that this regulating device shallbe acted upon directly by the fluctuations of current in the' ,c1rcu1t be tween generatorjA and conductors 4, 5, (iso that it-shall regulate in accordance with-the 'load'on that generator.

' The particular regulatlnl device F shown isadynamometenhav ngits 'xedand movable coils f'and f' connected in seriesinthe conf ductor 3 between the'ge'nerator A and the conductor 4 of the alternating-current Work circuit.

a current is directed through winding E The direction and ntens ty; of thiscurrent,-

and consequently the direction and value of the E. M. F. generated by booster E and the direction and amount. of current in the fgbattery, is dependent upon the direction and flhus any change 0fl0adj011 generator A [from that which may be considered its av;-

In the position shown the moving -ff'coil is at rightangles to the fixed coil, the

Ii -this position the current in the and 1t and none of it passes out throughpirsuit 12, because the potential at the points here 6 and'e-make contact with the segents c,- 0 is the same. If, however, the current increases or decreases the moving coil ot thedyna mometer will turn onits pivots to a F "one s ori'otherof the central position v shownfi Thus twopositionsare indicated in dotted lines','-,onebeing a position correspondking to an increase of current in themain generator and theother aposition corresponding to a main generator nine that the top of the connected to the positive side of the e cu: then when the mov- 'ng coil is in the ,fip sition with its contact 6' hearing against the upper portion offseg inents 0', cZ';,j. current Willfpass from convf 'rl'uctor 7 fot "the direct current circuitthrough conductor 11' and 'part'of the resistance r,

"At other times boosters E and E may be the booster the opposite direction. The

amtiunt of current passing through the booster field -W1ll, therefore,'be in proportion to the amount of current froln the alternating current circuit passing through the v dynamometer and, therefore, the booster E. M. F. will be responsive to the'fluctuati ons of current output of the alternating current generator.

Considering so much of the system as has 7 5 so far been described,- it will be seen that the arrangement permits the battery to ef-s fectively actas a compensating influence on generator A-to limit the variations of loadthereon. Thus if the load on working cir- 30 cuit 4, 5, 6 becomes heavy only a portion of and therefore thevo tagefin E is affected. 7

C represents a direc't-cuijrent generator connected with the battery'l) by'conductors 9 and 10. 13- andla are the conductors of a working circuit containing directcurre'nt translating devices. E is a booster similar generator C and inthe line This'booster. I control by a regulating device F which is acted upon .by variations in the electrical condition of the direct current circuit, and,

erator C. To this end it is'placed in conduct'or 9 between. the generator" Q and the point at which conductors 9 and 13'connect.

As shown this regulator F is 'conn'ectedinto conductor 9 and affects eoil E of booster E in precisely the-same way asregulator F is connected into conductor 3 and affects coil ER Further description of F is therefore unnecessary. By this arrangementbattery D acts to steady the loads on-both the alternating current and direct current genera- At'times boosters E andE' may be acting to cause a discharge from jthe'batter v into both working circuits simultaneously.

At still other times the relative loads onthe working circuits t, 5, 6 and I3, 14 may be such that both the prime sources A and C may be simultaneously supplying energy to one or the other :or the said working circuits. Indeed itmay he that'under certain conditions A, C' and D will all be simultaneously supplying-current to either of said working oincnits. :lt shonld be ng ted;
